anywhere you like, and I'll follow.

Ok, if there's compelling arguments *for* that caching
directive - excluding working around IE6's bug - and less
compelling ones, if any, *against* it, why aren't you sending
it in the first place? If, on the other hand, the arguments
lead you to decide on a different value, say 'public', which
one influences you more: those arguments, or IE6's bug? (I'm
not looking for answers here, since I could care less about
individual situations; just suggesting things to think about.)

Yes.

[By a strict interpretation of RFC2616, they'd have to fill
the form in again anyway. But I find that isn't always the
case in reality]
